HANGER FOR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 489,815, dated January10, 1893.

Application filed June 2, 1892. serial No. 135,299- (No model.)

To all whom it may concern.-

Be it known that I, CHARLES S. HUME, of Detroit, in the county of Beckerand State of Minnesota, have invented a new and Improved Hanger forElectric Lamps, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved hanger,more especially designed for use in connection with electric lamps, andarranged to permit of conveniently raising or lowering the lamp andholding it in the desired position.

The invention consists of certain parts and details, and combinations ofthe same, as will be hereinafter described and then pointed out in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a side elevation of the improvement with parts broken out;and Fig. 2 is a transverse section of the same on the line 22 of Fig. 1.

The lamp to be supported is attached in the usual manner to the socketA, held on the lower end of the electric light wire B, extending fromthe support 0, fastened to the ceiling or other place in the room. Onthe electric light wire B is tied or otherwise secured the lower end ofthe cord or string D, extending upwardly and passing through eyes E andE, projecting from a rod F, attached to a socket G, mounted to revolveon a supporting frame H, attached to the support 0. The cord or string Dafter passing the uppermost eye E extends to one side and passes throughan eye I, from which the cord passes onto a grooved pulley J, on the rimof which is secured one end of the said cord. As shown in the drawings,the cord D winds several times around the said grooved pulleyJ so as topermit of drawing the cord downward to the full extent of the length ofthe electric light wire 13. The pulley J is mounted to rotate loosely ona shaft or stud K, proj ecting from a bracket L, carrying the arm I, onwhich the eye I is formed. The bracket L projects from the socket G, aswill be readily understood byreference to the drawings. The pulleyJ ismade hollow and is connected at the inside of its rim with one end of aspiral spring N, fastened with its inner end to the fixed stud K. Itwill be seen that when the cord D is pulled, the pulley J revolves onthe stud K and thereby winds up the spring N so that when the pull onthe string is released, the spring returns the pulley J in the inversedirection to wind up the cord or string D. In order to somewhat brakethe pulley J, a spring 0 is provided, resting with its ends on one faceof the pulley J, the said spring being held on one outer end of the studK and pressed in contact with the pulley by a nut P, screwing on thethreaded end of the stud K against the middle part of the said spring.

The operation is as follows: When the several parts are in position asshown in Fig. 1, then part of the electric light Wire B hangs slackbetween thesupport O and the point where the string D is tied to thewire. Now, when it is desired to pull the electric lamp down into alower position, the operator pulls on the lamp or socketAwhereby a pullis exerted on the cord or string D, which thus unwinds from the pulleyJ, which latter rotates and winds up the string N. As soon as thedesired position is reached, the operator releases the electric lampwhich, by its weight, and that of the socket A, counterbalances thetension of the spring N so that the several parts remain in thisposition. When it is desired to again raise the lamp, the operator takeshold of the same, and by lifting it, releases the strain on the cord D,so that the spring N rotates the pulley J in the inverse direction, thuswinding up the said cord D. It will be seen that by tying the end of thestring D at different points on the electric light wire 13, the lamp maybe raised or lowered, as desired, the uppermost position being governedby the distance between the socket and that point on the wire on whichthe string D is tied. It is understood that when the lamp is in anuppermost position, the tied end of the string abuts against the underside of the lowermost eye E.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent,-

1. An electric lamp hanger, comprising a supporting frame, a bracketmounted to revolve on the frame, a spring actuated pulley carried by thebracket, a rod mounted to revolve with the bracket and provided witheyes, and a cord or string wound on the pulley and adapted to be securedto the electric light wire, substantially as described.

2. An electric lamp hanger, comprising a supporting frame, a bracketmounted to revolve on the frame and provided with an arm having an eye,a spring actuated pulley carried by the bracket, a rod mounted torevolve with the bracket and provided with eyes, and a cord or stringwound on the pulley and adapted to be secured to the electric lightwire, substantially as described.

3. An electric lamp hanger, comprising a socket mounted to revolve, andcarrying a bracket and a rod having eyes, a stud projecting from thesaid bracket, a pulley mounted to turn on the said stud, a springfastened with one end to the said stud and with its other end to thesaid pulley, and a cord winding on the said pulley and passing throughthe eyes, the said cord being adapted to be fastened to the electriclight wire, substantially as shown and described.

4. An electric lamp hanger, comprising a socket mounted to revolve, andcarrying a bracket and a rod having eyes, a stud proj ecting from thesaid bracket, a pulley mounted to turn on the said stud, a springfastened with one end to the said stud and with its other end to thesaid pulley, a cord winding on the said pulley and passing through theeyes, the said cord being adapted to be fastened to the electric lightwire, and a spring held on the said stud and engaging one face of thepulley to form a brake mechanism for the latter, substantially as shownand described.

5. An electric lamp hanger, comprising a socket mounted to revolve, andcarrying a bracket and a rod having eyes, a stud projecting from thesaid bracket, a pulley mounted to turn on the said stud, a springfastened with one end to the said stud and with its other end to thesaid pulley, a cord winding on the said pulley and passing through theeyes, the said cord being adapted to be fastened to the electric lightwire, a spring held on the said stud and engaging one face of the pulleyto form a brake mechanism for the latter, and means for adjusting thetension of the said spring, as set forth.
